> Skip schedule on not heartbeated nodes in Multi Node Placement
> --------------------------------------------------------------
>
> Key: YARN-10352
> URL: https://issues.apache.org/jira/browse/YARN-10352
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.3.0, 3.4.0
> Reporter: Prabhu Joseph
> Assignee: Prabhu Joseph
> Priority: Major
> Labels: capacityscheduler, multi-node-placement
> Attachments: YARN-10352-001.patch, YARN-10352-002.patch,

>
> When Node Recovery is Enabled, Stopping a NM won't unregister to RM. So RM
> Active Nodes will be still having those stopped nodes until NM Liveliness
> Monitor Expires after configured timeout
> (yarn.nm.liveness-monitor.expiry-interval-ms = 10 mins). During this 10mins,
> Multi Node Placement assigns the containers on those nodes. They need to
> exclude the nodes which has not heartbeated for configured heartbeat interval
> (yarn.resourcemanager.nodemanagers.heartbeat-interval-ms=1000ms) similar to
> Asynchronous Capacity Scheduler Threads.
> (CapacityScheduler#shouldSkipNodeSchedule)
> *Repro:*
> 1. Enable Multi Node Placement
> (yarn.scheduler.capacity.multi-node-placement-enabled) + Node Recovery
> Enabled (yarn.node.recovery.enabled)
> 2. Have only one NM running say worker0
> 3. Stop worker0 and start any other NM say worker1
> 4. Submit a sleep job. The containers will timeout as assigned to stopped NM
> worker0.
